reset DSP with WDT reset

Massimiliano Cialdi

Hi,

I use DM8168, with linux 2.6.37 coming from arago (http://arago-project.org/git/projects/?p=linux-omap3.git;a=commit;h=1d061a793577359bcc7fe9007d221e8028ba1a8f).

When WDT trigger a reset it seems that DSP isn't reset itself.

How to make DSP reset when WDT trigger a reset?

best regards

Max

    How exactly you define that C674x DSP core is not reset by the WDT? In DM816x datasheet (8.2 Reset) is stated that WDT resets everything except Emulation logic and do not latch sysboot pins.

    See if the below resources will be in help:

    DM816x silicon errata, Advisory 1.1.37 and Advisory 2.1.65
